Confidence Analysis
Moderate-confidence STS candidate. Two tankers (GULF PETROLEUM 4 and RIKER) maintained close proximity (min 187m, avg 189m) for 54 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Bosphorus/Dardanelles Approach, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (RIKER and GULF PETROLEUM 4) maintained close proximity (min 186m, avg 188m) for 63 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Bosphorus/Dardanelles Approach, a known STS activity area.
